Best Thermal Pads?

I'm not sure if this has been answered before but i keep getting a 'connection refused' every time i use the search function.

I did a repaste as well as changed the pads on my G72 (bought used last year) sometime last month because i noticed my temps weren't the best when gaming. Took it apart, got me some AS ceramique 2, and went to work.

My temps when i first bought the laptop were great, idle at 64c in an enclosed room for the whole day and while gaming, it would never go past 88-89c on stock clocks which was acceptable but after a few months that 64c would go to 72c idle and to 90's while gaming which is why i repasted.

My first application was, well, pathetic, with idling temps at 105c on the gpu (never am i ever spreading any compound around ever again...lol). Half an hour and one more try later the laptop was back together and i noticed i was now idling at 70c. (Ooh i forgot to mention this is all with the adapter plugged in, i lose a few degrees when on battery).

Fast forward to now where to do any gaming i had to remove the bottom panel of the laptop because my temps reach very high very fast and the gpu throttles. One mistake i made was when i first got it i never ran a furmark so i have nothing to compare it to,but with the bottom panel on, furmark will push the gpu to 101c where it begins to throttle and with the panel off, it will still get to 101c, just a bit slower than normal. Opened it again and the paste was fine, covered the GPU die well and whatnot, but the pads seem somewhat hard/cracked so i think that's where i messed up. I should have never removed the stock pads as they were fine to begin with.

to note, i bought these off ebay

I would do a copper shim mod but i'm not sure how messy that may end up being in the end. It would be fine for me but i'm looking to get the temps under control to get this laptop sold and want the next owner to have the least amount of stress possible if they aren't tech savvy, atleast for the first year of ownership.

Sooo, with all that said, i'm reaching out to the forum. Whats the best thermal pads that anyone has used to keep their temps under control and why? (price,performance, longevity?)

P.S. Interesting to note though that whenever i alt tab out of a fulllscreen game the temps drop down rapidly to around the high 70's and when i go back they shoot back up. When i first noticed the heat issue before i repasted and such, alt-tabbing would slowly (and i mean slowly) drop the temp a few degrees over the course of a minute or so.

 

I use Phobya thermal pads just simply because it's capable of doing 7W/mK.

 

I also have phobya , but its 1mm thick makes less contact with the gpu die , so its better to go with 0.5 mm thermal pads but it will be very hard to find those thermal pads with high conductivity .

 

Well thing is from what i read 1mm thickness pads are recommended for the G72 so that may not be a bad thing. Lol would you put your life on those pads? , i really don't want to open this thing any more than i have to and that being 1 more time

 

+1

If the ratings are correct Phobya has the best (I've searched around in the past and couldn't find better) Also, they're not at all hard to find:

Frozencpu is selling some Fujipoly 11.0 W/mK thermal pads on their site. Might be worth checking out

 

Just for the record the Vram on mobile cards does not get anywhere near hot enough for you to need to spend out loads on money on high quality pads. Vram temperature does not effect the memory controllers they are located in the DIE and I have tested lots and it makes no difference to your overclocking either. More important is the correct width to allow full contact between the Vram and the heatsink and proper application of compound on the DIE.

If you have a temperature problem because the pads are too thick you could test .5mm pads but you must make sure there is contact before stressing the card. ICD will fill any gaps as it is thicker than most. It sounds to me like application however go with the Pea method with a good blob of ICD and I reckon you will see a big difference.

 

I went with the pea method because that's the only way i could get complete coverage on the huge 260m die. Just to be safe i did it right, i disassembled the laptop once more and checked to make sure that all was well, then cleaned and reapplied once more. The replacement pads were nothing like what they were originally in the packaging (soft and malleable), it was, i dunno how to describe it, like hard clay/putty?

Top is 17W/mK... That's madness!!

 

Haha! I think those are used in space?

 

Curious what price they sell for? I would assume probably more than what the OP's 280M is worth

 

Well i don't see the price anywhere soo i'm guessing if we got to ask, we cant afford it

 

Anyways what i will try to do is order one phobya 1mm pad and report back here in a few weeks (shipping to me isn't fun) unless anyone has any other suggestions?

 

i want to replace those gummy pads but i am wondering how much milimeters thickness should i order ? 1mm , 1.5mm , 2mm , 2.5mm , 3mm , 4mm ?

0.3mm wont do any work ?

 

The stock ones are 1mm on the g73JH I went for .5mm to replace the gap caused by the heatsink but in places it did not fully contact with the heatsink so best to go with 1mm.

 

always helpfull thanks

these ones should do the trick ?

I used 0.5mm for the GTX460M on my G73JW, should be the same for G73JH and it'll improve the contact between the Die and the Heatsink. If you go for thiner pads you can consider using higher w/mk thermal paste (ICD7 is 4.5w/mk) since the contact is improved.

 

This one is 1mm (also have 0.5mm) and have same Thermal Conductivity: 3.2w/m-K

not sure with which one to go

 

I can finally reply after doing that repaste. I went with phobya 5 w/mk pads and now my temps are awesome.
Phobya Thermalpad Ultra 5W/mk - 1mm Products Model: PH-19053 [PH-19053] : Performance-PCs.com, ... sleeve it and they will come

I bought em from there cause frozencpu would not accept anything from my paypal (I'm from the caribbean).
My idle gpu temps are now at 62c WITH the bottom panel of the laptop on (with the ty pads that could only happen with the bottom panel off and a fan nearby) however a furmark stress test after 4 mins will still get me to 100c and im about ready to sell this and get myself a nice used G73 or any 17" with dual fans for that matter. Ill run some BF3 later to see how high the temps go
